Boost Muscle Growth

IsaLean PRO Shake is a complete, low-glycemic meal replacement with 36 grams of high-quality protein. It is great for individuals who are looking for increased muscle growth support or wanting to bust through weight-loss plateaus!

Whey protein is superior to other proteins for muscle growth and fat burning. Research also shows that whey protein supports maintenance of lean muscle mass, which supports long-term weight maintenance. Isagenix whey protein is pure, undenatured, and of the highest quality.

IsaLean PRO is not intended for use on Cleanse Days, however, IsaLean PRO is the perfect way to enhance — or even replace — your standard IsaLean® Shake on your Shake Days. It can be a great complement to your existing IsaLean Shake regimen, empowering your Shake Days so you can experience even greater results.

As we get older, our body's ability to absorb protein lessens, requiring more protein to hold on to muscle. Recent studies suggest that large doses of whey protein (up to 35g) versus lower doses over time is better for promoting muscle maintenance and growth in people over 55.
